StopBadware.org Website

We've all seen it happen: you or someone you know has downloaded something from the internet that seemed harmless enough at the time. Next thing you know, the computer has slowed to a crawl. Pop-up advertising starts to appear out of nowhere. Private information gets sent to some company you've never heard of. And the worst part? Trying to uninstall the software might only make the problem worse.
Welcome to the world of Badware.

And, "StopBadware.org is a 'Neighborhood Watch' campaign aimed at fighting back". Give them a stop-by.
